Millions of meniscus arthroscopies are performed every year, but for degenerative tears trials have shown no advantage over exercise therapy. When surgery can be avoided and when it is needed.

Types of meniscus tears

  • Degenerative — age-related, usually after 40; often found on MRI in people without pain.
  • Traumatic tears in the “red zone” (with blood supply) — in young people they are repaired whenever possible.
  • Bucket-handle tears — often lock the knee and need surgery.
  • Complex tears in the “white zone” — without blood supply, they hardly heal on their own.

Treatment without surgery

For a degenerative tear, the basis is an 8–12-week exercise programme and load adjustment. In the FIDELITY trial (NEJM 2013), Kise et al. (BMJ 2016) and ESCAPE (2022), exercise therapy gave results comparable to arthroscopy. Injections — corticosteroid, hyaluronic acid, PRP — may reduce pain and swelling, especially with coexisting osteoarthritis; there is no evidence that they restore the meniscus.

When surgery is still needed

  • the knee is locked and does not straighten fully;
  • a bucket-handle tear with mechanical symptoms;
  • knee instability combined with an ACL rupture;
  • a fresh traumatic tear in a young patient — repair is better than removal.

Outlook

In most patients with a degenerative tear, pain decreases within 2–3 months of exercise. If there is no improvement, the physician reviews the diagnosis — often the source of pain is osteoarthritis rather than the meniscus. More on the meniscus tear page.

Who it is not suitable for and possible risks

Contraindications

  • Active infection — at the injection site or systemic, with fever.
  • Active cancer or ongoing chemotherapy.
  • Blood clotting disorders or a low platelet count. Anticoagulants are discussed with the physician.
  • Pregnancy and breastfeeding — the procedure is usually postponed.
  • A corticosteroid injection into the same area in recent weeks.
  • Severe stage IV osteoarthritis with axial deformity and joint destruction — joint replacement is usually discussed instead.

Possible risks

  • Pain and swelling at the injection site for 1–3 days.
  • Bruising where blood or fat tissue is taken.
  • Rarely, infection. The procedure is therefore performed under sterile conditions with ultrasound or X-ray guidance.
  • The effect may be absent or smaller than expected.

If any of these apply to you, mention it in your request. The coordinator will check with the clinic physician whether treatment is possible. Contact a coordinator.

Scientific evidence

Studies of regenerative methods show mixed results. Clinic physicians rely on research including the following:

  1. Sihvonen R et al. Arthroscopic partial meniscectomy versus sham surgery for a degenerative meniscal tear. N Engl J Med, 2013.
  2. Thorlund JB et al. Arthroscopic surgery for degenerative knee: systematic review and meta-analysis of benefits and harms. Br J Sports Med, 2015.

Frequently asked questions

Can a meniscus tear heal without surgery?

Degenerative tears in people over 40 are mostly treated without surgery: trials found that exercise therapy gives results comparable to arthroscopy. Surgery is discussed for true locking and fresh traumatic tears.

How long does a meniscus tear take to settle without surgery?

Pain usually eases noticeably after 6–12 weeks of exercise. A tear in the area without blood supply does not grow back together, but the knee can function without symptoms.

When is arthroscopy needed for a meniscus tear?

For true locking when the knee cannot be straightened, for large flap or bucket-handle tears in young people and when 3 months of conservative treatment have not helped.

How does RegenPAS help organise treatment?

RegenPAS is a patient service centre in Munich, not a clinic. We review your images and symptoms and send a request to several partner clinics at once. Clinics that can accept you send their own conditions and price; prices differ between clinics, and you choose the option that suits you. The coordinator replies within 24 hours, and a clinic physician’s preliminary opinion follows in 1–3 business days. We then arrange the appointment, visa invitation, interpreter, transfers and accommodation. Treatment decisions are made by the clinic physician. Contact a coordinator.

How much does treatment cost and how long do I need to stay in Munich?

The cost depends on the method, the diagnostics needed and the clinic itself: prices differ between clinics. We request offers from several clinics and send you their conditions and quotes so you can compare. Price guidance is on the treatment cost page. For an outpatient procedure, 2–3 days in Munich are usually enough: examination, procedure and follow-up visit.
